ABSTRACT:
The invention relates to a torque metering device for a bicycle-type ergometer, in which ergometer the braking force is steplessly adjustable and in which the rotational movement is compensated by means of a flywheel. The rotational movement of the flywheel is braked by means of a brake mechanism (6, 7) which is pressed against the flywheel and moves limitedly therewith, whereby the movement of the brake mechanism with the flywheel is restricted by means of a spring balance connected to the brake mechanism and the frame structure of the ergometer. The spring force of the spring balance (9) counteracting the movement of the brake mechanism can be read on a scale (10) of the spring balance, which scale is positioned in the frame structure of the ergometer. In order to provide a reliable and easily readable metering device, the device is so constructed that it comprises a gear rack (12) stationarily fixed with respect to the frame structure. A pin member (13) is fastened on the moveable brake mechanism, the free end of which pin member is provided with a cog wheel (14) which is engaged with the gear rack (12). The indicator is formed by a sliding element (15) provided with a cogging which is engaged with the cog wheel so as to effect a movement of the indicator by means of the gear rack (12), the cog wheel (14) and the cogging of the sliding element (15), which movement exceeds that of the free end of the pin member (13). (FIG. 2)
